Abstract

Chromite is found as ubiquitous accessory grains and occasional segregations within dunite bodies. Results of analysis of chromite textures and chemistry and estimation of equilibration T of olivine-chromite pairs are cited as evidence that the dunites are metamorphic rocks rather than primary mantle peridotites. They are considered to be disrupted fragments of ophiolites that were emplaced before or during the peak of Ordovician metamorphism which was responsible for dehydration of serpentine-bearing rocks and alteration of chromite compositions and textures.-M.S.
